3 Increase facet limit PAZ-990
4 No longer a limit on facets.
6 Pazpar2-js no longer requires Apache2 PAZ-989
7 Package pazpar2-apache2 sets up everything WRT apache and only
8 package which requires it. pazpar2-apache depends on pazpar2-js.
12 Larger string buffer for forward address PAZ-987
13 Fixes buffer overflow that could occur if forward address is IPV6.
15 Updates to Windows NMAKE makefile for Visual Studio 2013.
19 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
20 include more details about the fault. Better install gdb and the
21 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
23 Per target timeout PAZ-981
24 New setting pz:timeout which overrides z3950_operation timeout
29 Re-introduce journal-subpart PAZ-980
30 Both citation and journal-subpart have same value.
34 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
37 Remove from js/pz2.js the code that translates just two diagnostic
38 codes (1 and 2) into human-readable messages. This is no longer
39 necessary at all, as PazPar2 has been returning the message as well as
40 the code in its responses since December 2012. Fixes PAZ-978.
42 primo xsl produces citation rather than journal-subpart PAZ-972
43 (fix in 1.8.1 was incorrect)
45 Fix missing .url files PAZ-977
46 Add missing .url+.cfg and add proper check for it.
50 Turbomarc needs number check for date 903 map PAZ-973
52 primo-pz2.xsl creates citation rather than journal-subpart PAZ-972
54 pz2.js: on successful search, issue a "show" command only if a show
55 callback function has been installed. Fixes part of PAZ-975
59 New command=stop which stops further search&retrieval for active
62 CF/primo XSL generates {volume,issue,pages}-number that are defined
63 in default Pazpar2 service definition. PAZ-968 PAZ-970
67 Various fixes for threaded operation PAZ-960 thru PAZ-966
69 Dump main configuration file during start of Pazpar2 PAZ-957
73 Log ingest failures and record failures:
75 Clean up logging PAZ-942
76 Use session lead in more places. Log hits/records/filtered for each
77 target when fetching is complete. Log hit count when a search
78 (response) is received. Remove some less useful log messages.
80 Fix warning about about missing (internal) stylesheet PAZ-956
82 Report number of filtered records in bytarget PAZ-954
84 Cache XML documents as they appear after normalization. The key
85 for the cache is database+record offset. Cache is removed if query
86 is modified for search. This speeds up re-establishing a result set
87 for databases where new query is same previous query.
91 poll: add assert for number of FDs; abort on poll failure
95 Fix hang for 2nd use of target with unresolved DNS PAZ-949
99 Use poll rather than select for main event loop to overcome limit of
100 1024 file descriptors PAZ-947
102 Override setting with same name (do not append) PAZ-945
106 Separate package: pazpar2-xsl PAZ-932
108 --- 1.6.44 2014/06/27
110 Update OPAC stylesheets for availabilityDate PAZ-943
112 Fix too funny startrecs description
114 Fix broken ~ match if filter contains = PAZ-941
116 --- 1.6.43 2014/06/12
118 Add pz:redis option for ZOOM caching using redis. This is an alternative
119 to memcached. Requires YAZ 5.2.0 to work.
121 --- 1.6.42 2014/05/06
123 Re-ingest native facets PAZ-934
125 Fix medium override for solr-pz2.xsl.
127 --- 1.6.41 2014/04/23
129 Fix URL with leading http:// not working PAZ-933
131 Build packages for Ubuntu Trusty Tahr 14.04 LTS
133 cf.xsl: handle medium override AND md field
135 --- 1.6.40 2014/04/10
137 sortmap relevance always uses increasing=1. PAZ-930
139 solr-pz2.xsl: ensure medium is also applied if Solr record do not
142 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
143 this code is only executed once.
145 Fix typos is sortmap documentation.
147 Doc: fix misplaced variablelist tag.
149 --- 1.6.39 2014/02/19
151 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
152 It's been like that since version 1.1.1 from August 2009.
154 Add support for result-set caching via memcached. See description of
155 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
157 Add support for a <metadata> container tag. Patfh from Sven Porst.
159 Add support for XInclude in main configuarion file. Patch from Sven Porst.
161 Add client_{lock,unlock} before call to non_block_events in
162 connection_continue. Problem is that if non_block_events fire records,
163 then we will not unlock client at all. And as a result, a dead-lock
166 --- 1.6.38 2014/01/07
168 Avoid removing slash and other characters for generic metadata that
169 looks like a URL (contains ://). PAZ-915
171 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
173 Cluster merge fixes. PAZ-901
175 Set client state to "working" when waiting for DNS resolver. PAZ-907
177 Log when session terminates. PAZ-905
179 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
180 Debian: add support for /etc/init.d/pazpar2 status
182 --- 1.6.37 2013/11/18
184 Fix 'Record Missing' for command=show PAZ-903
186 Preserve order of records within cluster PAZ-902
188 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
191 Allow clustered records to be ingested during retrieval. PAZ-900
193 Fix void function error which cannot return a value.
195 --- 1.6.36 2013/11/11
197 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
199 Upgrade to debhelper version 7 PAZ-898
201 Package with libyaz5 PAZ-897
203 Better error message for CCL parse errors PAZ-887
205 --- 1.6.35 2013/09/23
207 New target setting: pz:authentication_mode. PAZ-896
209 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
211 Strip #-suffix for ZOOM URLs. PAZ-892
213 --- 1.6.34 2013/08/30
215 Fix issue with hanging show/bytarget. Could happen if new search was
216 fired with filter before show from previous show completed.
218 Add 'date' handling for solr-pz2.xsl.
220 --- 1.6.33 2013/08/13
222 pz:authentication may carry user group password. If pz:authentication
223 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
224 authentication. Two forms are allowed
227 If no blanks are present, open authentication is in use (as before).
229 Fix {prev,next}recid elements that are returned by record
230 command. These were incorrect in versions 1.6.23 thru 1.6.32.
232 --- 1.6.32 2013/06/14
234 Experimental support for snippets. If argument snippets=1 is given
235 for command record or show, the text will include <match>-tags for
236 those area that matches.
238 Fix memory leak WRT client structures (incorrect inc ref count).
240 Log when a HTTP response is serialized and the time elapsed.
242 New command, service, which returns current service XML in use for
245 --- 1.6.31 2013/05/24
247 Local limit for fields of type "generic" (ie text fields) are
248 now normalized by mergekey rule before comparison takes place.
249 Before, no normalization took place and comparsion was, thus, exact.
251 New facility: dynamic rank , which allows ranking to be changed
252 for an existing result set. The rank can be set for search or
253 show. This overrides the rank for metadata elements (which fields
256 New facility:dynamic mergekey , which allows mergekey to be changed
257 for an existing result set. The mergekey can be set for search or
260 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
261 Also, allow ports to be given as names (not just integers).
262 Fix @-notation on systems that don't support IPV6 sockets.
264 --- 1.6.30 2013/04/26
266 Add MasterKey Connect configuration. Refer to section "non-standard
267 databases" for more information.
269 Allow timeformat for log to be specified with option -m (as Metaproxy
272 New Debian package pazpar2-dbg.
274 Fix NULL ptr reference of se->relevance. If a new search is initiated
275 and a CCL query fails to parse, Pazpar2 could crash.
277 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
278 existed in 1.6.29 only.
280 --- 1.6.29 2013/04/05
282 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
283 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
284 changed by setting "host" attribute for the "listen" element.
286 Change semantics of pz:extendrecs. Allow for repeated fetches .
287 pz:extendrecs is now the number of extra records to fetch (was total
290 --- 1.6.28 2013/03/21
292 Fix hang or memory violation if show occurred before a search. (not that
293 it makes much sense to perform a show before a search).
295 --- 1.6.27 2013/03/08
297 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
300 --- 1.6.26 2013/03/08
302 New pz:metadata attribute, empty="empty-value" for Pazpar2's
303 internal representation. With this attribute, Pazpar2 treates an empty
304 pz:metadata type as having the value for "empty" - if empty.
306 New setting, pz:extendrecs, which triggers extended fetch of records
307 for a database beyond pz:maxrecs for a show command.
309 Fix warning that was falsely issued for "missing limitmap".
311 Log message for Pazpart start/stop changed. Now using same style as
312 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
314 --- 1.6.25 2013/02/07
316 Fix hang of 2nd command=show with esn/syntax given.
318 --- 1.6.24 2013/01/18
320 New merge attribute type: 'first', which takes all metadata fields
321 from first target that returns the particular field.
323 --- 1.6.23 2013/01/02
325 Extend info command with hostname and YAZ SHA1
326 Indent results for both command stat and info.
328 Allow limit on merged content. The new configuration metadata
329 element, limitcluster, configures that a metadata element (name) be used
330 as limit name for search. Applies to the whole service (ie all targets),
331 unlike pz:limitmap which is configured per-target (database).
333 New feature: limitmap local:* matches against all metadata fields.
335 Allow repeated list in limitmap spec . Separated by comma. For
336 example: value="local:title,rpn:@attr 1=4".
338 New element <message> in bytarget response. Holds diagnostic message
339 of code (say 'Unsupported Use Attribute' for Bib-1 114).
341 Improved logging for record ingestion failures.
343 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
344 when YAZ is compiled without ICU support.
346 --- 1.6.22 2012/10/11
348 Requires YAZ-4.2.40 to support native solr support.
350 Fix and improve logic handling whether or not to re-do search on sort
351 order changes. A sort order with change in ascending/descending only
352 whould not trigger a new search, which is required for targets with
353 native sorting capabilities. Each client is now checked if instructions
354 (sortmap) exist for native sorting and only client that does requires
355 it is researched. Other clients is just re-ingesting the records,
356 they already have. The resultset is now cleared if any researching
359 Connection sharing between session has broken since version 1.6.8 with
360 introduction of logic that would minimize searching if pazpar2 could
361 detect this based on same query and limits and partly sort order.
362 This could lead to segementations violations.
364 Added a chapter in the manaul about relevance ranking.
366 --- 1.6.21 2012/09/24
368 Rank tweak: follow=number will increase mult by number if two terms
369 occur next to each other; number-1 if they are one term apart , .. 0
370 if they are number a part (all in order). Default is 0 (following
371 terms has no effect).
373 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
374 value given by lead and l is length from beginning of field where
375 term occurs (l=0 for first term, l=1 for second term, ..). Default
378 Rank tweak: length=strategy. length="linear" if mult is to be divided
379 by length (existing, default behavior), length="log" if mult is to be
380 divided by log2(1+length), length="none" if mult is not to be affected
383 --- 1.6.20 2012/09/21
385 Rank algorithm details may be printed as part of show response in
386 element <relevance_info>.. This is only printed if <rank debug="yes"/>
389 Record as returned by show/record command have a minimal indentation
390 which makes things human-readable.
392 New configuration of default sorting criteria (sort-default) in
393 service definition. If no criteria is defined it will be as before
396 Search command now supports sort parameter just as the show command.
397 If no parameter is give, it will use the service sort-default value.
399 --- 1.6.19 2012/09/18
401 Rank algorithm skips strings that gets normalized to empty string.
402 For example, & and ! could map to the empty string. The weight for
403 those terms is now 0 (as if they were not part of the query).
405 Rank algorithm does not use CCL from limitmap; only from the query
406 parameter (user query).
410 --- 1.6.18 2012/09/17
412 Rank algorithm configurable by 'rank' element inside service. So far
413 only, attribute 'cluster' is recognized. If cluster="yes", multiple
414 records inside a cluster boosts higher than single records. This
415 is default behavior and existing behavior. cluster="no" takes the
416 average score of each record in a cluster.
418 --- 1.6.17 2012/09/05
420 Fix bad re-use of connections (connections with changing proxy should not
423 --- 1.6.16 2012/08/22
425 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
426 resultset and sorting when the sort order is position. However this will be done on
427 every client poll, which will make pazpar2 continuing reset and fetching.
428 It should only be done on FIRST request where the sort order change.
430 Fix an issue on suggestion option: Also disable suggestions on empty string.
432 Clean up in turbo marc stylesheet.
434 Remove the hardcoded size of termlists.
436 --- 1.6.15 2012/06/27
438 New facility: ccldirective may be given in service definition. Allows
439 CCL parsing to be customized a bit, such as defining names of operators
442 New facility: raw record by checksum, rather than offset. The record
443 command optionally takes checksum which identifies certain record from
446 New facility: per field ranking. Rank may be given as M [F N] where
447 M is default rank and N is rank for CCL terms from field F.
449 --- 1.6.14 2012/06/04
451 Fix for IE7/8 in pz.js
453 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
455 Lower log level some places.
457 Remove some invalid test results.
459 --- 1.6.13 2012/05/23
461 Introducing a version=2 parameter for show, termlist and bytarget commands.
462 This enables pazpar2 to return approximation on hit and count count when
463 doing record filtering using the limit parameter on search and a
464 limitmap with a value of "local:"
466 Setting pz:xslt may embed local XSLT as an alternative to referring
468 Value is not CDATA but XML nodes embedded, so escaping is not necessary
469 but a root element *must* be present. For example:
470 <settings target="target="z3950.indexdata.com/marc">
479 Metadata field rank may given by XML internal document (pz:xslt
480 result). If rank is not given, the rank from service description is
483 Metadata field can now configured a default limitmap and facetmap.
484 Setting limitmap to "local:" would work for all kind of targets, but would
485 prob. not be the optimal solution. But at least better than the default behavior
486 of pazpar2 where no filtering is done.
488 A service definition can now also contains <set/> that defines service-wide
489 settings. These will override server-wide sets and will be overridded by
492 New setting, pz:present_chunk, that specifies number of records to fetch
493 at a time. Zero will disable chunkation; will fetch max_records at once.
495 --- 1.6.12 2012/03/14
497 Revert the format change in termlist response, that could break
498 some clients / UIs since they were expecting an (empty) element
499 if no facet values was found.
501 --- 1.6.11 2012/03/07
503 Revert the behavior of returning errors when unable to block
504 on termlist, bytarget and search, when unable to block due to
505 other block. The client will now receive a regular response,
506 but it will be logged in the server. A parameter (report) is
507 added to change behavior to return error response or WARNING
508 status message. Consider this "API" as private, as it is mostly
509 untested and could be changed in future releases.
511 Fix spell error in pz2.js fix in 1.6.10.
513 New Marc2TurboMarc.xsl (contribution from Sven Porst).
514 Can solve the missing marc21.xsl updates in some cases.
516 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
517 substring (contribtion from Sven Porst)
519 marc21.xsl: fix 1-based substring call
521 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
523 Add test_termlist_block to test suite
525 --- 1.6.10 2012/02/23
527 Fix SEGV for invalid PQFs and SRU/SOLR targets
528 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
530 Fix pz2.js: "null object" due to change in in bytarget result XML.
532 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
533 Added this normalization to the other subject-long fields (d6xx),
534 where it was missing.
536 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
537 Still differences around medium and holdings. marc21.xsl is not
538 longer active used by Index Data, and should be considered unsupported.
539 Use tmarc.xsl instead.
543 Fix SEGV that could occur for failed connections.
547 Fix bug for command sort that could return no results for active clients
548 (from previous search). This bug was present in 1.6.6-1.6.7.
550 Fix bug in results that could include results that should have been
551 filtered out. This bug was present in 1.6.6-1.6.7.
555 Fix bug introduced in 1.6.6 where a connection re-use could stall
558 Local filtering may now specify a local metadata field, eg.
559 pz:limitmap:somefield[t]=local:otherfield
563 For search, when limit and or filtering is in place and search
564 is identical to previous search, the result set is re-used and the
565 target is not searched.
567 Limits may work perform local filtering as well, by using "local:"
572 Updated bytarget command to contain a suggestions element with misspelled
573 words and suggestions to these. pz2.js has been updated to deliver this
574 onwards as well. Only target that currently delivers this is the solr
575 client in YAZ 4.2.18.
579 New service definition element, xslt, that allows an embedded stylesheet
580 to be defined. This can be referred to from pz:xslt as an alternative to
583 New pz:sortmap:field setting for specifying hints on how to make
584 a target natively sort on a field. This is used for command=show in
585 conjunction with sort.
587 New pz:url setting for specifying the actual URL for a target. When
588 this is used the target ID is not used as URL anymore and the target ID
589 may be almost any string (not including []).
591 command=termlist without name parameter returns all termlists/facets.
592 Previously if name parameter was omitted, only "subject" was returned.
596 Make termlist sorting stable. Terms with same frequency are now sorted by
597 their display name. This makes a pretty display and improves our
598 regression test because qsort is not a stable sort.
600 New sort parameter value 'position'. The 'position' sorts merged records
601 by their original position from the remote target. This is primarily useful
602 for debugging and may be used for targets that already perform some kind
603 of relevance ranking. Note that sort by default is decreasing; so to get
604 records in their original order sort=position:1 must be used.
608 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
610 Facility to change working directory for pazpar2 daemon. Option -wdir
611 sets working directory to dir. This facility is useful if core dumps
612 must be saved. In this case, the current working directory must be
613 writable by the running user, such as "nobody".
617 New configuration element <icu_chain> for <server>/<service> which
618 allows a named ICU rule (chain) to be defined. The names relevance,
619 sort, mergekey and facet are used for those operations. The definition
620 <icu_chain id="sort" locale="en"> .. </icu_chain>
622 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
623 And so on.. for relevance, mergekey and facet as well. The latter
624 style is deprecated. The facet terms are normalized by the facet
625 rule by default. This may be changed on a metadata field basis by
626 defining the new attribute 'facetrule' for the metadata element.
628 <icu_chain id="myrule" locale="en"> ... </icu_chain>
629 <metadata name="author" termlist="yes" facetrule="myrule"/>
631 Preserve rorder for merged metadata. Fixes issue as reported by Sven
632 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
634 tmarc.xsl: set journal-subpart to 773$ only.
638 Modify the behavior for the limit parameter (first defined in 1.5.7).
639 Mapping of limit searches are now defined by the new configuration item
640 pz:limitmap. Fix a dead-lock problem with the limit parameter.
642 Extend tmarc.xsl to extract 773$g data (OpenURL).
646 ICU default maps remove backquote (`).
648 Command 'search' takes limit parameter (optional). The limit parameter
649 allows a search to be limited one or more facets and the corresponding
650 values. This is for server side filtering.
652 Configure tweak: Use -lm for log(3) if needed
656 Fix a problem with skiparticle sortkey that could be completely
657 ignored (and reduced to "").
659 Fix dependency problem in pazpar2 RPM package (did not require
660 libyaz4 as it should).
664 Fix memory leak that occurred for command=termlist&name=xtargets .
666 Pazpar2 may save HTTP requests. Enabled by option -R.
670 Experimental support for DTIC DADS target. New dads-pz2.xsl.
672 Support for query_syntax (overrides the default for SRU | Z39.50)
674 Support for extraArgs (ZOOM "extraArgs" option) for targets
676 New commands: status-server and status-session
680 Fix for threaded runs: Client now have a copy of the database URL,
681 which can used after the database has been release from the client.
682 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
684 tmarc.xsl: Add journal-title-abbrev and full text.
686 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
688 Fix for cmd=record before search.
690 Session Logging clean up.
692 Fix wrong termlist factor when maxrecs is different from 100.
696 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
697 Term factor is default enabled but can be diseabled by
698 pz:termlist_term_factor=0
702 Add scaling of facet count. Currently always enabled, needs fixing.
703 Allow user-defined info for target suffix. This has no meaning in
704 Pazpar2 except to distinguish targets from each other. The suffix
705 data begins with #. For example z3950.indexdata.com/gils#Mydata
707 Added exact-match recordfilter; format name=value
711 SOLR support. Pazpar2 may operate as web service client for SOLR.
715 Fix for show command and block=1 (dead lock). Bug was introduced in
720 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
721 tested on CentOS 5.5 only.
725 Fix problem with result sets being removed from a client session
726 if the connection for it was resused by another session. Bug #3489.
728 New iphone UI for Pazpar2 (www/iphone).
732 Fixes for threaded operation.
734 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
736 New example services in etc/services in source. In the Debian packages
737 these are located in /etc/pazpar2/services-available
739 Threaded mode operational on Windows. Requires Windows 7 or Windows
742 Default value of setting pz:max_connections is 0 which means that there
743 is no limit on number of connections.
747 Pazpar2 may operate in threaded mode. Enabled by element threads in
748 the configuration. See pazpar2_conf for details.
750 New setting setting: pz:max_connections. Setting pz:max_connections is
751 a limit of number of sockets to a host. When this limit is reached,
752 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
753 The client will be marked Client_Error when it can not be searched
754 (other clients in a session may work). If pz:max_connections is not set
755 for a target, a value of 30 will be used. Note: the pz:max_connections
756 will only work in threaded mode.
758 pz2.js: JSON support for show.
760 Debian package: Enable default service, default.xml, before starting
761 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
765 Debian version depends on on libyaz4. Note that Pazpar2 will still
766 compile from source with YAZ 3.
768 Split services into separate files. The example configuration file
769 pazpar2.cfg.dist now includes a default service default.xml (part of
770 etc). And default.xml includes settings/edu.xml. The default.xml file,
771 not to be confused with settings/defaults.xml, is a template for jsdemo
772 and other services. The Debian package installs /etc/pazpar2/server.xml
773 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
774 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
775 The default.xml (from etc) is installed in /etc/pazpar2/services-available
776 and a symlink to it is created from services-enabled. The default.xml
777 service is unnamed and, thus, will be used by jsdemo and test1.
779 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
780 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
784 Support for additional fields in cf.xsl and pazpar2.conf.dist:
785 publisher, available, due, location (=locallocation), callno
786 (=callnumber), thumburl and score.
788 Describe pz:xslt and the auto setting.
790 Move mergekey definition away from the normalization stylesheets and
791 define a mergekey common for all target types in pazpar2.cfg.
793 Code update: Use the Odr_int type for hit counts. This is part of
794 YAZ 3.0.47 and later and so configure checks for that.
798 Metadata attribute 'skiparticle' also works for ICU based
799 normalization. (was only working for the non-ICU/ASCII before).
801 Command bytarget with argument settings=1 will show settings per
802 target.. This is to be able to verify correct settings and be able to
803 test that they are correct. The database settings array size is now
804 also stored.. Problems with database settings array is that if not
805 careful it will be too small (smaller than dictionary per-service
808 Make record list sorting stable by comparing mergekey for records if
809 relevance/title or other sorting criteria all match. This is merely to
810 ensure that our regressions tests works (reproducible output).
812 Relevance calculation changes: use a different denominator (length) for
813 per-field relevance scoring.. Instead of length of all ranked fields we
814 now use length of individual fields (as if they were individual "free"
815 text fields). This will ensure that documents with a long field with no
816 match (say description) will not "hurt" a title match.
818 Diagnostic member was not set on connection error. Fixed
822 Command search takes two optional parameters, startecs and maxrecs,
823 that specifies the start offset (0, 1, ...) and maximum number of records
824 to fetch for each target.
826 XSLTs + MARC maps are cached within a session so we don't re-parse
827 them over and over again. Even for a session with a single search
828 there's much to be gained because many targets use the same
831 The metadata attribute 'mergekey' now takes one of three values 'no',
832 'required', 'optional' . And the resulting mergekey from metadata
833 is now ordered in the same way as metadata in the service definition.
834 Older Pazpar2 version use the order in which metadata appeared in a
837 The search argument 'filter' now offers a new operator ~ which does a
838 substring match. The = operator works as before: string match for
839 anything but pz:id, or target match for pz:id.
841 New setting pz:recordfilter. The value of this setting takes the
842 form name[~value]. This setting makes Pazpar2 ignore all retrieved
843 records that do not have the metadata element name with value substring
846 Pazpar2 allows YAZ log level to be set (option -v).
850 For WS responses Pazpar2 creates XML header. Exception: raw record.
852 Setting XML files are now stored in etc/settings instead of etc. This
853 reflects the layout with the Debian package layout.
855 Settings may be posted for command=settings. The POSTed settings must
856 have root element 'settings' like regular setting files. In order to be
857 recognized, the POST request must use Content-Type=text/xml.
859 A service may be posted for command=init. This service will be used
860 during the session. The service may have its own target settings,
861 ICU config, timeout, etc. In order to be recognized, the POST request
862 must use Content-Type=text/xml.
864 Timeout values may be given per-service. That's element 'timeout'
865 which takes three attribute values (a subset may be given): 'session',
866 'z3950_operation', 'z3950_session'. Option -T is no longer supported
867 - used to specify session timeout.
869 Option -t tests the Pazpar2 configuration and returns exit code
870 (0=success, non-zero=failure). In previous version of Pazpar2, -t
871 specified local settings.
873 In version 1.2.0 the configuration file - after include processing -
874 was dumped to stdout. Now, the configuration is only dumped to the
875 yaz log file if option -d is given.
879 Configuration may now have multiple server areas. This means that a
880 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
881 yet supported - on a server basis. Configuration may also have multiple
882 services .. That is repeating service elements inside a server. Each
883 has an attribute 'id' which serves as service ID. This ID in turn may
884 be used in a Pazpar2 session, by specifying parameter service=ID for
885 command init. There can be at most one unnamed service inside a server
886 which can be referred to by not specifying an service ID for command
887 init (backwards compatible). In order to partition multiple servers and
888 services a new include directive has been added. This takes an attribute
889 'src' which specifies one or more sub-files. For example to include
890 service files, one might use:
891 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
892 It is the intention that that completely makes the settings directive
895 Fix problem where the record command would wait forever if there were
896 no targets to wait for (activeclients == 0).
900 One result set is created per session (last search) rather than for
901 each connection which happen to be shared (bug #3009).
903 marc21 stylesheets changed for efficiency.
907 Session timeout may be specified on the command-line as option -T.
909 Pazpar2 may now be operated in a no-merged mode for records.. All records
910 will be considered unique. This mode is enabled if no mergekey is
911 generated by the normalization stylesheet (pz:xslt).
913 Pazpar2 caches original records from each target and the 'record' command
914 with offset returns the original record if 'syntax' and 'esn' are NOT
915 specified. This speeds up retrieval of original records but also means
916 that Pazpar2 uses more memory. The cached records will be freed when the
917 session terminates or a new search is executed.
919 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
920 library part of YAZ is used.
922 Added SRU client support.
924 Automatically computes pz:nativesyntax if not provided. Works for XML and
927 --- 1.0.13 2008/11/24
929 Command bytarget returns name of target (if defined).
931 --- 1.0.12 2008/11/04
933 Fixed bug #2021.. location now holds all brief elements.
935 --- 1.0.11 2008/10/15
937 Fixed check for application/x-www-form-urlencoded parameters.
939 --- 1.0.10 2008/10/14
941 Fixes for IE in pz2.js.
943 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
947 Changed the JS library pz2.js to use POST for long URL (+ params).
949 Added installation instructions for Windows. Note: NT services is
950 NOT available until we make a new release of YAZ.
952 Preserve order of repeated metadata fields (they were reversed before).
954 More MARC21 information extracted for metadata.
958 Fixed bug #1162: HTML entities are not escaped properly.
960 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
964 Marc21 stylesheet updated to reflect multiple full text fields
968 Fixed bug in pz2.js WRT DOMElement attributes on IE.
970 Fixed bug 2100: Database wildcards not working
974 Added support for retrieval of records in binary.
976 Fixed bug 1794: Pazpar2 does not return valid XML.
978 Deal with ICU not returning sortkey (resulted in SEGV before).
982 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
983 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
985 Improved diagnostics when Pazpar2 HTTP decoding fails.
987 Pazpar2 requests may be POSTed as using Content-Type
988 application/x-www-form-urlencoded.
990 Pazpar2 honors LF in HTTP headers.
992 Handle targets that handle negative hit counts (should not happen, but it
997 ICU is used for tokenization and normalization of the following: mergekey,
998 sorting, relevance terms.
1000 Debian package now enables ICU tokenization and normalization by default.
1002 --- 1.0.2 2007/08/22
1004 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1005 ways: Either as parameters to the normalization stylesheets (which would allow the
1006 programmer to postprocess or use the values in any way) or after the normalization
1007 step, in which case values are made part of the normalized record (and available for
1008 sorting, termlists, display, or other interface-related use.
1010 Implemented sorting by year.
1012 Option -d dumps records to the current log file instead of stderr.
1014 Fixes for compilation on cygwin.
1016 Z39.50 client code uses pz:elements. pz:elements was recognized in
1017 earlier Pazpar2 versions but it was not used for anything.
1019 icu_chain_test is using fgets instead of getline - fixes compilation
1022 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1023 query conversions fail (rather than _any_). This means targets that do
1024 not support some fields are ignored in a search.
1026 --- 1.0.1 2007/07/03
1028 Improved handling of socket timeout for Z39.50 connections.
1030 Misc documentation updates and spell fixes.
1032 Debian package pazpar2 creates log rotate entry.
1034 Debian package pazpar2-apache2 reloads Apache2.
1036 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1039 --- 1.0.0 2007/06/20
1041 First public release.
